Figure Nl Shaffer Spm Valve Regulators

Each subsea control pod contains two regulators - one to regulate pressure for the ram preventers and one to regulate the pressure for operating the annular preventers. Some control systems incorporate a third regulator so that the operating pressure of each annular preventer can be individually manipulated.

Typical regulators are 1 l/2" hydraulically operated, stainless steel, regulating and reducing valves. As shown in Fig 9.11 the output line of each regulator is tapped and the pressure roused back to a surface gauge through the umbilical. This readback pressure is used to confirm that the subsea regulator is supplying the power fluid at the pressure set by the pilot surface regulator.
